[0001] This utility model relates to the field of filter technology, and in particular to a Y-type disc filter that facilitates observation of clogging. Background Technology

[0002] Disc filters are widely used in industrial and commercial fields, such as food, textile, metallurgy, plastics, pharmaceuticals, building materials, papermaking, HVAC systems in industrial and commercial buildings, irrigation, wastewater treatment, sewage reuse, municipal water supply, waterworks, large power plants, chemical enterprises, and emergency filtration. Among them, Y-type disc filters, as a key purification device in pipeline systems, are widely used in agricultural irrigation, industrial circulating water, and domestic water supply.

[0003] Existing Y-type disc filters have the following technical problems during use: the clogging status of the filter element inside the filter cannot be directly observed, requiring the system to be stopped and the equipment disassembled for inspection, which affects maintenance efficiency; under conditions of fluid pressure fluctuation and pipeline vibration, axial loosening easily occurs between the filter element and the housing, and between the bottom cover and the housing, leading to sealing failure and decreased filtration performance; the drain end cover lacks an effective anti-loosening structure, which can easily lead to leakage risks after long-term operation. Therefore, a Y-type disc filter that facilitates the observation of clogging status is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a Y-type disc filter that facilitates observation of blockage. It aims to solve the problem that in the prior art, the bottom cover and the drain end cover of the Y-type disc filter are prone to loosening due to pipeline vibration during long-term use, resulting in sealing failure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a Y-type stacked filter for easy observation of clogging, comprising a housing, a horizontal tube fixedly connected to the top of the housing, a bottom cover threadedly connected to the bottom of the housing, a stacked filter element disposed inside the housing, an observation window fixedly connected to the front of the housing, and a pressing mechanism disposed inside the bottom cover.

[0006] The pressing mechanism includes a fixed ring and a movable sleeve. The inner wall of the movable sleeve is slidably connected to the outer wall of the fixed ring. The inner wall of the movable sleeve is rotatably connected to a rotating shaft via a bearing. A top plate is fixedly connected to the upper end of the rotating shaft. A first spring is provided between the movable sleeve and the fixed ring.

[0007] As a further description of the above technical solution: the outer wall of the fixed ring is fixedly connected to the inner wall of the bottom cover, the upper end of the first spring abuts against the inner wall of the movable sleeve, and the lower end of the first spring abuts against the inner wall of the fixed ring.

[0008] As a further description of the above technical solution: the top of the top plate abuts against the lower end of the stacked filter element, the outer wall of the movable sleeve is provided with a guide hole, and the inner wall of the guide hole is slidably connected with a guide block.

[0009] As a further description of the above technical solution: the outer wall of the guide block is fixedly connected to the outer wall of the fixed ring, and the number of guide holes is four, with the four guide holes being equally spaced on the outer wall of the movable sleeve.

[0010] As a further description of the above technical solution: a drain port is provided at the lower end of the bottom cover, and an end cap is threadedly connected to the outer wall of the drain port.

[0011] As a further description of the above technical solution: a pressing mechanism is provided at the lower end of the rotating shaft, the pressing mechanism including a limiting cylinder, the top of the limiting cylinder being fixedly connected to the lower end of the rotating shaft.

[0012] As a further description of the above technical solution: the inner wall of the limiting cylinder is slidably connected with a stop block, and the inner wall of the limiting cylinder is provided with a second spring, the upper end of the second spring abutting against the inner wall of the limiting cylinder, and the lower end of the second spring abutting against the top of the stop block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the elastic compensation effect of the first spring in the top pressing mechanism enables the top plate to generate a continuous axial pressing force on the stacked filter element. Combined with the anti-rotation constraint of the guide block and guide hole, the problem of loose threads between the stacked filter element and the shell, and between the bottom cover and the shell caused by pipeline vibration is effectively solved, ensuring the stability of the filter sealing structure and the filtration accuracy.

[0016] 2. In this utility model, the abutment block, abutment plate and fixing rod driven by the second spring in the pressing mechanism apply an independent axial pre-tightening force to the end cover, thereby realizing the anti-loosening function of the sewage end cover, avoiding the risk of liquid leakage caused by the loosening of the end cover under working vibration, and improving the reliability of equipment operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1The present invention provides an embodiment of a Y-type disc filter for easy observation of blockage, comprising a housing 1, a horizontal tube 4 fixedly connected to the top of the housing 1, a bottom cover 5 threadedly connected to the bottom of the housing 1, a disc filter element 9 disposed inside the housing 1, and an observation window 6 fixedly connected to the front of the housing 1. The observation window 6 allows the user to easily observe the blockage of the disc filter element 9. A pressing mechanism 2 is disposed inside the bottom cover 5. The pressing mechanism 2 can generate axial pressure on the disc filter element 9 and the bottom cover 5 to prevent the bottom cover 5 and the disc filter element 9 from loosening due to pipeline vibration.

[0028] Reference Figure 2 - Figure 4 The pressing mechanism 2 includes a fixed ring 201 and a movable sleeve 202. The inner wall of the movable sleeve 202 is slidably connected to the outer wall of the fixed ring 201. The inner wall of the movable sleeve 202 is rotatably connected to a rotating shaft 203 via a bearing. The upper end of the rotating shaft 203 is fixedly connected to a top plate 204. The rotatable setting of the top plate 204 can prevent the bottom cover 5 from rubbing against the bottom end of the stacked filter element 9 when it is rotated for installation and removal. A first spring 205 is provided between the movable sleeve 202 and the fixed ring 201. The first spring 205 can generate an upward thrust on the movable sleeve 202, so that the top plate 204 presses against the bottom of the stacked filter element 9.

[0029] Reference Figure 4 - Figure 6 The outer wall of the fixed ring 201 is fixedly connected to the inner wall of the bottom cover 5. The upper end of the first spring 205 abuts against the inner wall of the movable sleeve 202, and the lower end of the first spring 205 abuts against the inner wall of the fixed ring 201. The top of the top plate 204 abuts against the lower end of the stacked filter element 9. The outer wall of the movable sleeve 202 is provided with a guide hole 206. The inner wall of the guide hole 206 is slidably connected with a guide block 207. The guide hole 206 and the guide block 207 can play a limiting and guiding role for the movable sleeve 202. The outer wall of the guide block 207 is fixedly connected to the outer wall of the fixed ring 201. There are four guide holes 206, and the four guide holes 206 are equally spaced on the outer wall of the movable sleeve 202.

[0030] The bottom cover 5 has a drain port 7 at its lower end. The outer wall of the drain port 7 is threaded with an end cover 8. The drain port 7 facilitates the discharge of impurities accumulated inside the bottom cover 5.

[0031] Reference Figure 3 - Figure 4 , Figure 7 The lower end of the rotating shaft 203 is provided with a pressing mechanism 3. The pressing mechanism 3 includes a limiting cylinder 301. The top of the limiting cylinder 301 is fixedly connected to the lower end of the rotating shaft 203. The pressing mechanism 3 can generate axial pressure on the end cover 8 to prevent the end cover 8 from loosening and causing liquid leakage due to pipeline vibration.

[0032] The inner wall of the limiting cylinder 301 is slidably connected to the abutment block 302. The inner wall of the limiting cylinder 301 is provided with a second spring 303. The upper end of the second spring 303 abuts against the inner wall of the limiting cylinder 301, and the lower end of the second spring 303 abuts against the top of the abutment block 302. The setting of the second spring 303 can generate a downward abutment force on the abutment block 302.

[0033] A fixing rod 304 is fixedly connected to the inner wall of the end cover 8. A stop plate 305 is fixedly connected to the upper end of the fixing rod 304. The top of the stop plate 305 abuts against the lower end of the stop block 302. The axial pressure generated by the second spring 303 can be transmitted to the end cover 8 through the fixing rod 304 and the stop plate 305.

[0034] Working principle: Fluid enters the housing 1 through the horizontal pipe 4, is filtered by the disc filter element 9, and is then transported downstream. Impurities are trapped on the surface of the disc filter element 9. The user can directly check the degree of clogging of the disc filter element 9 through the observation window 6 on the front of the housing 1. When drainage is required, the end cap 8 is unscrewed, and the impurities deposited in the bottom cap 5 are discharged from the drain port 7.

[0035] Working principle of the top pressing mechanism 2: The first spring 205 applies an upward pushing force to the movable sleeve 202. The movable sleeve 202 transmits the axial force to the top plate 204 through the rotating shaft 203 connected by the bearing, so that the top plate 204 continuously presses against the lower end of the stacked filter element 9. The guide block 207 on the outer wall of the fixed ring 201 slides with the guide hole 206 on the outer wall of the movable sleeve 202 to form a circumferential limit, ensuring that the movable sleeve 202 can only move axially and cannot rotate, thereby preventing pipeline vibration from causing the threaded connection between the stacked filter element 9 and the housing 1, and the bottom cover 5 and the housing 1 to loosen.

[0036] Working principle of the pressing mechanism 3: The second spring 303 applies downward pressing pressure to the pressing block 302 inside the limiting cylinder 301. The pressing block 302 transmits the pressure to the pressing plate 305. The pressing plate 305 applies axial pressure to the inner wall of the end cover 8 through the fixing rod 304, so that the threaded connection between the end cover 8 and the drain port 7 remains tight under vibration conditions, and avoids the end cover 8 from loosening and causing leakage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
